TECHNICAL FIELD

The present invention relates to the field of liquid crystal displaytechnology, and particularly to an array substrate, a liquid crystalpanel and a liquid crystal display device.

DESCRIPTION OF RELATED ART

The liquid crystal display (LCD) device is a type of an ultrathin flatdisplay device, and the liquid crystal panel is an important part of theliquid crystal display device. Generally, the liquid crystal panel atleast includes oppositely-disposed array substrate and color filtersubstrate and a liquid crystal layer arranged between the arraysubstrate and the color filter substrate. The array substrate is formedwith a pixel array and mutually intersected data lines and scan lines.The data lines are configured to supply data signals to the pixel array,and the scan lines are configured to supply scan signals to the pixelarray. In a traditional array substrate, pixels in a same column areconnected to a same data line and thereby the data line is responsiblefor supplying data signals to all the pixels in the same column; pixelsin a same row are connected to a same scan line and thereby the scanline is responsible for supplying scan signals to all the pixels in thesame row. Moreover, in the array substrate, there are various types ofarrangement designs for the data lines and scan lines, and one of thearrangement designs can reduce a half of data lines, i.e., thearrangement type of data line share (DLS)

FIG. 1 is a schematic partial structural view of a conventional DLSarray substrate. In particular, the array substrate is formed with anarray of sub-pixels P11, P12, P13, P22, P23 and mutually intersecteddata lines D1˜D5 and scan lines G1˜G6. Horizontally adjacent sub-pixelsin the array share one data line (e.g., P12 and P13 share the data lineD2, P22 and P23 share the data line D2), so that the number/amount ofthe data lines is reduced to be a half of the data lines of thetraditional pixel array. Adjacent sub-pixels in a same row are connectedto different scan lines (e.g., P12 and P13 are respectively connected tothe scan lines G1 and G2), sub-pixels in a same row spaced by onesub-pixels are connected to a same scan line (e.g., P11 and P13 both areconnected to the scan line G2), and vertically adjacent sub-pixels areconnected to different scan lines (e.g., P12 and P22 are respectivelyconnected to the scan lines G2 and G3), so that the number/amount of thescan lines is twice of that of the traditional pixel array.

Since the number of the scan lines is doubled, the scan time assigned toeach scan line is reduced, so that the charging time of sub-pixel isreduced. Current liquid crystal panel generally adopts the dot inversiondriving method, i.e., signal polarities of adjacent two data lines areopposite and signal polarities of adjacent rows of a same data line alsoare opposite. Since the data line has a certain resistance, the datasignal would have the delay and distortion of waveform duringtransmission on the data line, resulting in a charging ratio differenceof sub-pixels in adjacent columns of the data line. Referring to thedriving signal waveform diagram as shown in FIG. 2, D(odd) is a signalwaveform of an odd data line, D(even) is a signal waveform of an evendata line, the signal polarities of D(odd) and D(even) are opposite. Inthe driving signal waveform diagram, the dashed line is the theoreticalsignal waveform diagram, and the solid line is the actual waveformdiagram formed after the delay and distortion. When D(even) is the dataline D2, with reference to FIG. 1, when G1˜G4 are sequentially turnedon, the D2 sequentially charges the sub-pixels P12, P13, P22 and P23,the D2 charges two sub-pixels P12, P13 or P22, P23 in one signalpolarity period. However, in one signal polarity period, owing to thesignal distortion, the previously charged sub-pixels P12, P22 areinsufficiently/poorly charged and thus have a relatively low brightness,and the latterly charged sub-pixels P13, P23 are well charged and thushave a relatively high brightness, so that significant bright and darklines are generated. Accordingly, the whole liquid crystal panel wouldgenerate multiple alternate bright and dark vertical lines and thus thedisplay quality is degraded.

Based on the above situation, there is a need of improving the brightand dark lines of liquid crystal panel.

The array substrate includes an array of sub-pixels andmutually intersected a plurality of data lines and a plurality of scanlines. By way of the arrangement design of a connection manner of thesub-pixels with the data lines and the scan lines, when is driven by adot inversion driving method, each column of sub-pixels would haveintervally arranged well-charged sub-pixels and poorly-chargedsub-pixels.

For the connection manner of the sub-pixels with the data lines: in theplurality of data lines, each two data lines define a column grouparranged therebetween, and each column group includes two columns ofsub-pixels.

For sub-pixels in an odd column group, each sub-pixel is connected toone of the two data lines at two sides of the odd column group which iscloser to the sub-pixel (i.e., the closer one data line). For sub-pixelsin odd rows of an even column group, each sub-pixel is connected to oneof the two data lines at two sides of the even column group. Forsub-pixels in even rows of the even column group, each sub-pixel isconnected to one of the two data lines at two sides of the even columngroup which is father to the sub-pixel (i.e., the farther one dataline). Herein, “closer” and “farther” are relative terms.

For the connection manner of the sub-pixels with the scan lines:firstly, in the plurality of scan lines, top and bottom of each row ofsub-pixels respectively are disposed with two scan lines only fordriving the row of sub-pixels; and then the array of sub-pixels isdivided into a plurality of row groups, and each row group includes onerow or two rows of sub-pixels.

Specifically:

For sub-pixels in even column groups of each row of an nth row group,each sub-pixel is connected to the scan line on top of the row ofsub-pixel (i.e., top scan line); and for sub-pixels in odd column groupsof each row of the nth row group, each sub-pixel is connected to thescan line on bottom of the row of sub-pixels (i.e., bottom scan line).

For ith and (i+1)th sub-pixels in each row of an (n+1)th row group, eachsub-pixel is connected to the scan line on top of the row of sub-pixels;and for jth and (j+3)th sub-pixels in each row of the (n+1)th row group,each sub-pixel is connected to the scan line on bottom of the row ofsub-pixels.

For sub-pixels in odd column groups of each row of an (n+2)th row group,each sub-pixel is connected to the scan line on top of the row ofsub-pixels; and for sub-pixels in even column groups of each row of the(n+2)th row group, each sub-pixel is connected to the scan line onbottom of the row of sub-pixels.

For jth and (j+3)th sub-pixels in each row of an (n+3)th row group, eachsub-pixel is connected to the scan line on top of the row of sub-pixels;and for ith and (i+1)th sub-pixels in each row of the (n+3)th row group,each sub-pixel is connected to the scan line on bottom of the row ofsub-pixels.

Where, n=1, 5, 9, . . . , n−4, n; i=2, 6, 10, . . . , i−4, i; and j=1,5, 9, . . . , j−4, j.

For the above described connection manner of the sub-pixels with thescan lines, when each row group includes two rows of sub-pixels, theconnection manner of one row of sub-pixels in the row group with datalines and scan lines is the same as the connection manner of the otherone row of sub-pixels in the row group with data lines and scan lines,i.e., two rows of sub-pixels are used as a repeating unit.

In order to make that the objectives, technical solutions and advantagesof the invention will be more clearly understood, the invention will befurther described by embodiments thereof with reference to accompanyingdrawings.

[Embodiment 1]

FIG. 3 is a schematic partial structural view of an array substrateprovided by this embodiment. Hereinafter, Pxy represent specificsub-pixels, where x=1˜4, y=1˜8. For example, in FIG. 3, P11 is the firstsub-pixel at the top-left corner, and P48 is the last sub-pixel at thebottom-right corner.

As shown in FIG. 3, in data lines D1˜D5, each two data lines define acorresponding one of column groups 11, 12, 13, 14 arranged therebetween,and each column group includes two columns of sub-pixels, e.g., thecolumn group 11 in FIG. 3 includes the first and the second columns ofsub-pixels.

In particular, for the sub-pixels in the odd column groups 11, 13, eachsub-pixel is connected to one of the two data lines at two sides of thecolumn group which is closer to the sub-pixel, e.g., for the sub-pixelsin the column group 11, the sub-pixels P1 y are connected to the dataline D1, and the sub-pixels P2 y are connected to the data line D2. Forthe sub-pixels in odd rows of the even column groups 12, 14, eachsub-pixel is connected to one of the two data lines at two sides of thecolumn group which is closer to the sub-pixel, e.g., for the sub-pixelsP13, P14 in the first row of the column group 12, the sub-pixel P13 isconnected to the data line D2, and the sub-pixel P14 is connected to thedata line D3. For the sub-pixels in even rows of the even column groups12, 14, each sub-pixel s connected to one of the two data lines at twosides of the column group which is farther to the sub-pixel, e.g., forthe sub-pixels P23, P24 in the second row of the column group 12, thesub-pixel P23 is connected to the data line D3, and the sub-pixel P24 isconnected to the data line D2. Herein, “closer” and “farther” arerelative terms.

In scan lines G11˜G14 and G21˜G24, top and bottom of each row ofsub-pixels respectively are disposed with two scan lines only fordriving the row of sub-pixels, e.g., the scan lines on top and bottom ofthe first row of sub-pixels respectively are G11, G21, and the scanlines G11, G21 only are for driving the first row of sub-pixels.Moreover, the array of sub-pixels is divided into row groups 21, 22, 23,24. In this embodiment, each row group includes one row of sub-pixels,i.e., the row group 21 includes the first row of sub-pixels, the rowgroup 22 includes the second row of sub-pixels, and so on.

The connection manner of sub-pixels with the scan lines will bedescribed as follows.

For sub-pixels in the even column groups 12, 14 of the row group 21,each sub-pixel is connected to the scan line on top of the row ofsub-pixels, e.g., for the sub-pixels P13, P14 in the even column group12 of the row group 21, the sub-pixels P13, P14 both are connected tothe scan line G11. For sub-pixels in the odd column groups 11, 13 of therow group 21, each sub-pixel is connected to the scan line on bottom ofthe row of sub-pixels, e.g., for the sub-pixels P11, P12 in the oddcolumn group 11 of the row group 21, the sub-pixels P11, P12 both areconnected to the scan line G21.

For ith and (i+1)th sub-pixels in each row of the row group 22, eachsub-pixel is connected to the scan line on top of the row of sub-pixels,e.g., for the second and third sub-pixels P22, P23 in the row group 22,the sub-pixels P22, P23 are connected to the scan line G12. For jth and(j+3)th sub-pixels in each row of the row group 22, each sub-pixel isconnected to the scan line on bottom of the row of sub-pixels, e.g., forthe first and fourth sub-pixels P21, P24 in the row group 22, thesub-pixels P21, P24 are connected to the scan line G22. Herein, i=2, 6;j=1, 5.

For sub-pixels in the odd column groups 11, 13 of each row of the rowgroup 23, each sub-pixel is connected to the scan line on top of the rowof sub-pixels, e.g., for the sub-pixels P31, P32 in the odd column group11 of the row group 23, the sub-pixels P31, P32 both are connected tothe scan line G13. For sub-pixels in the even column groups 12, 14 ofeach row of the row group 23, each sub-pixel is connected to the scanline on bottom of the row of sub-pixels, e.g., for the sub-pixels P33,P34 in the even column group 12 of the row group 23, the sub-pixels P33,P34 both are connected to the scan line G23.

For jth and (j+3)th sub-pixels in each row of the row group 24, eachsub-pixel is connected to the scan line on top of the row of sub-pixels,e.g., for the first and fourth sub-pixels P41, P44 in the row group 24,the sub-pixels P41, P44 are connected to the scan line G14. For ith and(i+1)th sub-pixels in each row of the row group 24, each sub-pixel isconnected to the scan line on bottom of the row of sub-pixels, e.g., forthe second and third sub-pixels P42, P43 in the row group 24, thesub-pixels P42, P43 are connected to the scan line G24. Herein, i=2, 6;and j=1, 5.

Each sub-pixel Pxy is connected to a corresponding data line and acorresponding scan line by a switching element 10. Specifically, thesub-pixel P13 is taken as an example, as illustrated in FIG. 4, theswitching element in this embodiment is a thin film transistor (TFT). Agate 10 a of the TFT is electrically connected to the corresponding scanline G11, a source 10 b of the TFT is electrically connected to thecorresponding data line D2, and a drain 10 c of the TFT is electricallyconnected to the sub-pixel P13.

When a dot inversion driving method is employed, the charging of thesub-pixels P12, P13, P22, P23, P32, P33, P42, P43 at two sides of thedata line D2 is taken as an example, with reference to FIG. 3, G11, G21,. . . , G14, G24 are sequentially turned on, the sub-pixels P12, P13,P22, P32, P33, P42 are charged by the data line D2 and the sub-pixelsP23, P43 are charged by the data line D3. For the sub-pixels in the Px2column, P12 and P42 are well-charged sub-pixels, while P22 and P32 arepoorly-charged sub-pixels. For the sub-pixels in the Px3 column, P33 andP43 are well-charged sub-pixels, while P13 and P23 are poorly-chargedsub-pixels.

An array substrate provided by this embodiment of the invention can beregarded as a structure obtained by repeating the partial structure asshown in FIG. 3 along transversal and longitudinal directions multipletimes. FIG. 5 shows a distribution of well-charged sub-pixels andpoorly-charged sub-pixels of the array substrate with the structure in aframe of image. In FIG. 5, the white areas represent well-chargedsub-pixels, and the shaded areas represent poorly-charged sub-pixels. Itcan be found that, the sub-pixels in a same column have intervallyarranged well-charged sub-pixels and poorly-charged sub-pixels, and thesub-pixels in a same row also have intervally arranged well-chargedsub-pixels and poorly-charged sub-pixels. Accordingly, in a liquidcrystal panel including the array substrate, brightnesses of variousareas are balanced on the whole and thus the drawback of the existenceof bright and dark vertical lines can be improved.

[Embodiment 2]

FIG. 6 is a schematic partial structural view of an array substrateprovided by this embodiment. What is difference from the embodiment 1 isthat: in this embodiment, along the arrangement direction of the scanlines, the sub-pixel array is divided into row groups 21 a, 22 a, 23 a,24 a, each row group includes two rows of sub-pixels. Specifically, asillustrated in FIG. 6, the row group 21 a includes the first and thesecond rows of sub-pixels, the row group 22 a includes the third and thefourth rows of sub-pixels, the row group 23 a includes the fifth and thesixth rows of sub-pixels, and the row group 24 a includes the seventhand the eighth rows of sub-pixels.

A connection manner of one row of sub-pixels in each row group with datalines and scan lines is the same as a connection manner of the other onerow of sub-pixels in the row group with data lines and scan lines, thatis, two rows of sub-pixels are used as one repeating unit. For example,in the row group 21 a, for all the sub-pixels in the first and thesecond rows, vertically adjacent two sub-pixels (e.g., P11 and P21) havea same connection manner, and the connection manner of all thesub-pixels in the first and the second rows with the data lines and thescan lines is the same as the connection manner of the row group 21 ofthe embodiment 1, and thus will not be repeated herein. Likewise, therow group 22 a is corresponding to the row group 22 of the embodiment 1,the row group 23 a is corresponding to the row group 23 of theembodiment 1, and row group 24 a is corresponding to the row group 24 ofthe embodiment 1.

An array substrate provided by this embodiment can be regarded as astructure obtained by repeating the partial structure as illustrated inFIG. 6 along transversal and longitudinal directions multiple times.FIG. 7 shows a distribution of well-charged sub-pixels andpoorly-charged sub-pixels of the array substrate with the structure in aframe of image, the white areas represent the well-charged sub-pixels,and the shaded areas represent the poorly-charged sub-pixels.
